Slow upload in DMVPN

Hi Everyone

Happy New Year!

We have Client they have DMVPN network from 3 offices to Central hub site.

One office has 10MB Wan connection from the ISP to Hub site and it is new setup.

Router port connected to ISP is hard coded as full duplex and speed of 10 as ISP also have  hard coded at their end.

When users did test  from there PC the download speed is upto 8 MB but upload seed is only half MB.

Setup at office is as below

PC---Switch ----Router ---ISP Router.

I checked the CPU utilization on switch and router it is normal.

Wan port has no errors.

Need to know is there any thing i can do on my end to increase the upload speed?

Hi Mahesh,

Download speed of 8Mb on a 10Mb circuit is not bad.  Regarding your upload speed, talk to your ISP.  Some ISPs with give a lager bandwidth for download then upload.  If you have a contract/SLA with ISP for 10 up and 10 down, then open a ticket with the provider, so they can run some tests on your circuit and send you the results.  Also, make sure your router can handle the speed and it is configured correctly.
